CodeIgniter(CI)省略头index.php配置

配置网站的根目录中的.htaccess文件配置

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule>

其中起最主要作用的是

<IfModule mod_rewrite.c>
             RewriteEngine On
             RewriteCond %{REQUEST_FILENAME} !-d
             RewriteCond %{REQUEST_FILENAME} !-f
             RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
